CABBURETER.

Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed August 12, 1908. Serial No. 448,127.

'1. tively, of the city of New York, boroug the Bronx, in the cbunty andState of New York, and of Vaulx en Velin, France, have invented a newand Improved Carbureter, of which the following is a full, clear, andexact description.

T his invention relates to carbureters such I as used on automobiles forproducing an explosive mixture of air andgas.

` The object of the invention is to produce a device f this kind whichis simple in construction, and which will operate electively to producea' thorough evaporation of the gasolene or other fuel in largequantities, and

i vaporizers,

which will ailord means for nicely regulatingl the vaporization ofthegasolene and theproportion of gas andair which passes from thecarbureter to the engine.

More speciiically, the invention contemplates the use of a plurality ofevaporators or which operate through theiry capillarity. to draw thegasolene from a reservoir vsothat the same may be evaporated in acurrent. of warm air passing through the carbu: retei' From thevaporizing chamber in which these vaporizers are placed, the charged airpasses into a mixer through a regulator, and through this mixer is drawna qixiantitv of free air which mixes` with thc c argebefore itpass'esfrom the carbureter.

vThe invention consists in the construction and combination of parts tobe more fully dei scribed hereinafter and particularly set forth i'n theclaims.

' indicate corr Reference is to be" had to the accompany'- lingdrawingsforming a part of this specificatipn,i1n which similar characters ofreference 'esponding parts in all the ligures.

' Figure "1" is a vertical section through a carbureter .constructedaccording to o ur invention; Fig. 2 is aside elevation of thecarbureter; Fig. 3` is a horizontal cross section through thecarbureter; and Fig. 4 is a de- -tailvlewfshowing a split ring in sideelevation, which ring constitutes a feature of the invention. Y

Referring mor represents the fu lindrical form, presenting1 an upperhead 2 anda lower head 3. T e-upper head 2 is particularly to the parts,l e

chamber, which is of cy-v formed with a plurality of circular openings4, which are boredconically, with the large side of the opening'disposed downwardly. Similar openings 5 are provided in alinement withthe openinvs 4, in the lower head 3, and these are of smajler diameter,as shown most clearly at'the right in Fig. 1. The fuel receptacle orreceiver 1 is formed centrally into a conical thimble 6, whichconstitutes a mixer for the charged air and free air.

Upon the head 3 there is seated a dshcd head or bonnet 7, which isformed with a cenits upper side so as to for the rim of the receiver andthe lower edge of the thimble 6, respectively, as shown. ln cach of theopenings 5 there is mounted a tube oi air duct 11, and these tubes areheld in place by any suitable means such as that shown. 'lhe upper endsof these tubes extend up through the openings 4', as indicated at theleft in lfig. 1. On the' exterior of cach tube, and telescoped over itas shown, there is provided a vaporizcr 12, which lis of tubular formand com )used of wire mesh or similar material. n the exterior of thisvaporizer 12 there is placed a vaporizing sleeve 13, of cotton or afabric formed of a similar highly capillary fiber. These sleeves ofsplit rings 14, which are formed below with conical heads 15 seating inthe conlcal bore of the openings 4, as indicated. lhe

e so as to be enfiaged by (damping nuts or nut rines 16 whic i seat uponof the lead 2, as shown. By screwing u on thesenuts 16, the split rings15 will tubes'11, and the degree of pressure exerted at` this point willregulate the capillary action of the v aporizers in a manner which willbe described more fully hereinafter. The gasolenc or similar' liquidfuel-is supplied to the receiver 1 through the tubular inlet 17 arranvedon the side wall thereof, as shown.

dish'ed head 7 is formed into a conical seat the seat by a downwardmovement, the lower end, of the cone 19 being turned conically soy as tofit the conical seat 18. This 'valve 19 is disposed within the thimble6, as indicated, the side walls of-thevalve and thimble beingrarrangedso that an annular 13 are vclamped at the openings 4 by meansI u perends of these split riiws 15 are thread-i the upper side clamp thesleeves 13 securely against the trally disposed inlet neck S, and isbored on form seats 9 and 10 roo 'll-lie middle portion of the bonnet ori 18 for a conical valve 19 which comes upon mixing space 20 is formedbetween them. The valve 19 is attachedl to the lower end of a verticalstem 21 which passes upwardly through a globe elbow 22, said elbowhaving a horizontal delivery neck 23 which leads to the enginecylinder.-

The vaporizers are all incased 'drical hood 24-.Which seats on the upperside of the receiver 1. The lower portion of the elbow 22 is formed intoa threaded opening which screws upon a threaded neck 25 formed on theupper end of the thimble 6. This neck projects through the hoodv andaffords means for attaching the globe elbow 22,V shown. 'In the upperportion of the thimble and within the vaporizing chamber v26,vvhicl:iisl formedl within the hood 24, there is'provided a plurality ofopenings 27 disposed circumferentially in the vwall of the 28,' whichconsists simply of a ring'havin openings 29 which may all aline simulta.

.l neously with the openings 27 if thering is placed in the properposition. The position of the ring vis controlled by means of a handle30 which passes radially through a slot 31 in the wall of the hood, asindicated in Fig. 2. The slot Slis kept closed by a sliding cover orplate 32, which ts closely upon the curved face of the case. In order toinsure that the handle 30 will remain in any posi tion in which itisleft, we provide a spring clip ori friction clip 33, which is attachedto the side-ofthe case as indicated in Fig. 3. This clip exerts pressureupon the plate or yslide 32, and holds it frictionally againstdisplacement.

The bonnet 7 is'provided at one side, asindicated in'Fig. 2, with 'anvinlet mouth 34 throughwhich warm air is drawn into the carbureter belowthe head when the device is in operation. `With this Iend in view, the'intake 34 Vmay be disposed near a heated point of the engine, so thatthe air drawn in- Wardly will be warmed before it passesinto 50y thecarbureter. As indicated in Fig. 2, the bonnet 7 and the hood 24 arefirmly held in position by bolts which pass through lugs 36 formed inalinement on the hood and bon' net.

There may be as many of the vaporizers as p desired. The gasolen'eenters-the fuel charnber or receptacle 1 by the tube 17. On account oftheir capillarity, 'the sleeves 13 absorb the fuel, and elevate or feedit into the vaporizi/ngchar'nber 26. If the nuts 16 are tightly screwedup, they will compress or 'clamp the split rings 15 upon thev sleevesinA such a way as to reduce-V or choke their caplllary action. lThe warmair entering the bonnet 7 passes up the tubes 11 and effectin acylinmiXer--lonyt'himble 6. Through these open#- of the mixer which niceregulation between ively evaporates the fuel in the vaporizers; the gasthus formed in the vaporizing chamber is then entrained through theopenings 27 by the free air which is drawn up through the mixer. The1proportion of the gas to the-air to forni the c arge is nicelyregulated by the ring 28 and the valve 1.9. A thorough mixture of thegas and air takes place in the mixer. The ring 29 may be regulated afterthe engine is running so as to reduce gradually the proportion ofgasolene; the reduction being continued just to the point beyond whichthe charge fails to explode. This is the most leconomical operatingpoint.

Special attention is called to the relatively large area of thecapillary sleeves with the air current passing upwardly through them;and attention is called, also, to'the Aconstruction presents aconstantly reducing cross section beyond the regulator 28. In this lvvayan intimate mixture of the charged as and the air is produced.

Specia lattention is called to. the conical 'form of the valverIQ. Asthis valve becomes 'morele'nd more elevated, its

conical face approaches the openings 27 so-that the freedom of flow ofthe current of vapor through these openings is restricted. In this way avery and air may be obtained.
